Welcome to this little website. My name is Yorhel a.k.a. Yoran Heling a.k.a. Ayo. I spend a fair amount of my free time developing and contributing to free and open source software. This website is home to several of these projects.
This site isn't really a complete portfolio. There's a bunch of projects for which I never got around to creating a homepage, and some others that have an entire website of their own. A slightly more complete list can be found on my cgit instance, but that isn't entirely comprehensive, either.
I hope that you will find something useful among the selection of software or the incidental article on this site. Enjoy your stay!

Validation schemas defined this way can also be used for JSON coercion, HTML5 validation pattern generation and code generation for Elm - but those features are all still somewhat experimental and undocumented.
